Both the extension and the helper need version scripts to prevent symbols from being exported. -fvisibility=hidden is not sufficient because it's not being applied to some of the static libraries they link against. On the extensions side: the path to the version script was wrong, as this error was ultimately ignored because invalid ld options were being ingored. This resulted in some extra zai_* functions being exported. On the helper side. Symbols from libunwind, libc++ and possibly others were being exported.
